Software

I write software for fun and for a living. For me software development is as
much a passion as a source of income. Most of the software I write in my spare
time and some of the software written for my clients is released as Open Source.
You can find some of it on my GitHub page.

I believe that a good programmer needs to know many programming languages.
Knowing several languages and different programming paradigms helps with
solving different problems. I routinely write software in C++, Ruby,
Javascript, and Perl. I have also used (to varying degrees) many other
languages like Java, C, SQL, Python, PHP, XSLT, R, ... and have related skills
like writing shell scripts, makefiles and regular expressions.

Flinch

A web link checker that will tell you about broken links on your web
site. It automatically keeps track of all links and only tells you
about problems when they persist for several days, so that you don't
get annoying emails every time a site is down temporarily. I wrote
Flinch more than 10 years ago in Perl and it still does it's work
for me every day.

OSMCoastline

OSMCoastline is used to extract coastline data from OpenStreetMap
and bring it into an easily usable format. It is needed for most
kinds of OSM maps to create land (or water) polygons. OSMCoastline
is written in C++ using the Osmium framework.

Osmium

Osmium is a fast, flexible and comprehensive C++ and Javascript
toolkit for working with OSM data. It can, among other things, read and
write OSM files in different formats, assemble way and multipolygon
geometries and convert OSM data into shapefiles and other output
formats.

Taginfo

OpenStreetMap uses tags to add meaning to geographic objects.
Taginfo collects information about these tags from the OSM database,
the OSM wiki, and other sources to help you understand what they mean
and how they are used. It is written in C++ and Ruby. You can see taginfo
in action at taginfo.osm.org.
